In the XML from the printer, I have a tag
<dd:TotalImpressions PEID="5082">1234</dd:TotalImpressions>
so the xml_grep command here is looking for that tag (dd:TotalImpressions) with the attribute, PEID=“5082”.
xml_grep 'dd:TotalImpressions[@PEID="5082"]' http://[Your_Printer_IP_Address]/DevMgmt/ProductUsageDyn.xml --text_only
Hi @EventuallyFixed
Thanks for your help. I pasted all your code
I have the tag in the xml file : <dd:TotalImpressions PEID=“5082”>424</dd:TotalImpressions>
Here is the result of the command line xml_grep
When I launch the automation, this error appears
Command failed: date -d '2020-10-25 1 month' +%Y-%m-%d
For the xml_grep: Are there two tags with ‘<dd:TotalImpressions PEID=“5082”>’? If so, that is why there are two answers. Do you have a unique tag & attribute in the document that can be used, one which increments every time a page is printed? If so use that.
If not you could try something like adding | head -qn1, or | awk 'NR==1{print $1}’ to take only the first line of the output:
xml_grep 'dd:TotalImpressions[@PEID="5082"]' http://[Your_Printer_IP_Address]/DevMgmt/ProductUsageDyn.xml --text_only | head -qn1
or
xml_grep 'dd:TotalImpressions[@PEID="5082"]' http://[Your_Printer_IP_Address]/DevMgmt/ProductUsageDyn.xml --text_only | awk 'NR==1{print $1}'
For the date: Your OS is not doing the date calculation. Please tell me what OS and shell are you using? For the shell, drop to the OS and give the output from this:
echo "$SHELL"
Also, the result of this could be helpful:
ls /bin/bash
To get the date part working, it would be easier for you to use the Template Sensor instead of the command line sensor. So change this:
# hp_envy_5540_next_renewal_date:
# friendly_name: HP Envy 5540 Next Renewal Date
# value_template: >-
# {% if (states('input_datetime.hp_envy_5540_this_period_start_date').split("-")[1]|int + 1 > 12) %}
# {{ (states('input_datetime.hp_envy_5540_this_period_start_date').split("-")[0]|int + 1)|string + "-01-" + states('input_datetime.hp_envy_5540_this_period_start_date').split("-")[2] }}
# {% else %}
# {{ states('input_datetime.hp_envy_5540_this_period_start_date').split("-")[0]|int|string + "-" + ('%02d' % (states('input_datetime.hp_envy_5540_this_period_start_date').split("-")[1]|int + 1)) + "-" + states('input_datetime.hp_envy_5540_this_period_start_date').split("-")[2] }}
# {% endif %}
to this, uncommenting the code by removing the ‘#’ at the start of the line:
hp_envy_5540_next_renewal_date:
friendly_name: HP Envy 5540 Next Renewal Date
value_template: >-
{% if (states('input_datetime.hp_envy_5540_this_period_start_date').split("-")[1]|int + 1 > 12) %}
{{ (states('input_datetime.hp_envy_5540_this_period_start_date').split("-")[0]|int + 1)|string + "-01-" + states('input_datetime.hp_envy_5540_this_period_start_date').split("-")[2] }}
{% else %}
{{ states('input_datetime.hp_envy_5540_this_period_start_date').split("-")[0]|int|string + "-" + ('%02d' % (states('input_datetime.hp_envy_5540_this_period_start_date').split("-")[1]|int + 1)) + "-" + states('input_datetime.hp_envy_5540_this_period_start_date').split("-")[2] }}
{% endif %}
and then change this:
- platform: command_line
name: "HP Envy 5540 Next Renewal Date"
command: "date -d '{{ states('input_datetime.hp_envy_5540_this_period_start_date') }} 1 month' +%Y-%m-%d"
value_template: "{{ value }}"
to this, commenting-out the code by adding a ‘#’ at the start of the line
#- platform: command_line
# name: "HP Envy 5540 Next Renewal Date"
# command: "date -d '{{ states('input_datetime.hp_envy_5540_this_period_start_date') }} 1 month' +%Y-%m-%d"
# value_template: "{{ value }}"
Thanks for all your help !
echo "$SHELL"and ls /bin/bash
gives me /bin/bash
I’m confused, why I need to comment the xml_grep command line to get the date part working ?
I’m confused, why I need to comment the xml_grep command line to get the date part working ?
It’s me that is confused! 
I’ve corrected the code substitution above.
What is your OS? Is it HassOS? Raspbian/Raspbery Pi OS? Some other OS? I ask because it’s OS differences that are causing the command-line date sensor to not work. I’m using Raspbian, which by default uses the bash shell.
Hi,
I have tried as well for 2 days to get your solution running. Unfortunately I am not familiar linux/unix, so I guess I belong -meanwhile - to the majority using HassOS simple installation via image on SD card.
As soon as there is a code working with HassOS, I might try it again. But I do now better stick to the initial solution without page carryover.
Finally, it seems to work without errors 
I still have to configure according to my subscription.
I have a last (I hope) question : why “Printed Pages Total at month start” has a minimal value to 500 ?
hi, I have hassos and this code works for me:
hp_envy_6230_next_renewal_date:
friendly_name: "HP Envy 6230 Prossima Data Rinnovo"
value_template: >-
{% if (states('input_datetime.hp_envy_6230_this_period_start_date').split("-")[1]|int + 1 > 12) %}
{{ (states('input_datetime.hp_envy_6230_this_period_start_date').split("-")[0]|int + 1)|string + "-01-" + states('input_datetime.hp_envy_6230_this_period_start_date').split("-")[2] }}
{% else %}
{{ states('input_datetime.hp_envy_6230_this_period_start_date').split("-")[0]|int|string + "-" + (states('input_datetime.hp_envy_6230_this_period_start_date').split("-")[1]|int + 1)|string + "-" + states('input_datetime.hp_envy_6230_this_period_start_date').split("-")[2] }}
{% endif %}
and if you don’t have it yet, created this sensor:
- platform: time_date
display_options:
- 'time'
- 'date'
No reason other than I had just over 500 printed pages at the time ot was created. You can change that.
For completeness, I have amended the configuration as follows:
hello, since it is now a bug-free code, would it be feasible to create a package? so as to have everything in order and easy to understand for other users.
Good idea. However I’d have to learn how to do that, and for the foreseeable future my time is rather limited.
Hi @EventuallyFixed
Where can I find the new configuration to gest the total number of pages printed with HA objects ?
Thanks
It’s all in the post above.
Sorry, I did not see.
I had problems with the xml_grep command but thanks to this new code, everything works
Thank you so much!
As you suggested, I made this into a package file.

Hi Vendo232, the pages left sensor is evaluated from this template: -
{{ states('var.printer_pages_at_month_start')|int - states('sensor.hp_printer_printer')|int + 50 }}
Check what value you have for sensor.hp_printer_printer and then change the intitial_value for var in your configuration file, so that you get the correct start point.
it works!, thank you Adam
btw both solutions work great the Counter and Var option.
I`m using the latest HA 2021.4.1
Hello
Has anyone tried converting automation to nodered?
Thanks
